You don’t need to have the latest iPhone model in order to enjoy the newest features in iOS 9, but you will need an iPhone 6s or an iPhone 6s Plus if you want to take advantage of the extra functionality afforded by 3D Touch technology. Also known as Force Touch, this allows the touchscreen on the newest iPhone to detect varying levels of pressure. There’s a difference between tapping on the screen and pressing on it a little harder.

In effect, 3D Touch on the iPhone 6s can be utilized one of three different ways. If you press down harder on an app from the main screen, you can bring up the Quick Actions menu. Inside of an app, if you press down on certain items, you can “Peek” into them. Press even harder and you can “Pop” into them. Exactly how this works will vary between apps and developers will continue to update their apps to support 3D Touch. In the meantime, here are six of the best iPhone apps that use 3D Touch right now.

Instagram

Largely credited for popularizing the notion of image filters, particularly for square-format images, among modern smartphone users, Instagram has been updated to support 3D Touch. If you press down firmly on any username (or the user’s avatar), you’ll be able to Peek into their profile page to get the name, follower information, and recent photos. What’s more, while you’re Peeking, you can slide your finger up to reveal a contextual menu to quickly follow or unfollow the user, as well as send a direct message. While in your app listing, you can press down hard to Quick Access the new post screen, activity feed, or direct message inbox.

Dropbox

While there are so many other cloud storage services available on the Internet these days, Dropbox continues to be an industry leader thanks to its great file synchronization and robust mobile apps. In the case of the iOS app, it has now been updated for 3D Touch too. When you’re browsing around your cloud-based files, you can Peek to preview one of your files and Pop to open it completely. This is great for not only pictures, but documents and other file types too. And don’t forget to setup 2-step verification for your Dropbox account!

OpenTable

Whether you’re planning a business trip in another city or you’re staying right in your own hometown, locating restaurants and making reservations through OpenTable is incredibly convenient. You get the added bonus of earning rewards for every reservation that you complete. When looking through a list of restaurants, you can Peek to glimpse at a map with its location and slide upwards to get shortcuts for making a reservation within the next hour. For more information, you can Pop to actually open the page for that restaurant.

Evernote

Incredibly useful for both professional and personal use, Evernote is one of the best note-taking apps around. It predates alternatives like Google Keep and it comes with a wealth of robust features. Now with support for 3D Touch, the Evernote app allows you to open up a Quick Actions menu from the home screen, as well as the ability to Peek into your notes without actually opening them. Once inside a note, you can Peek into links too.

WhatsApp

Easily one of the most popular cross-platform mobile messaging apps out there, WhatsApp takes advantage of 3D Touch in a very obvious and convenient way. When someone sends you a picture through the app, for instance, you can “Peek” to preview the full image and “Pop” to view the full-size version. The same can be said about any videos you may receive, as well as links, contact cards and locations. That’s far faster than having to open every attachment and then going back into the conversation. For the time being, it is not possible to “Peek” into a conversation without opening it completely from the conversation list.

Spark

Offering a more effective and efficient way to manage your emails, Spark helps you rifle through your inbox “faster than ever before.” If you have an iPhone 6s, you can Peek into emails while in your message listing, as well as Peek into attachments when you’re inside any individual message. From the home screen, the Quick Actions menu makes it really quick to compose a new email, search for a message, or hop right into your inbox.
